Question

to make a solute dissolve more quickly in a solvent, which would you do​

Answer 1

To make a solute dissolve quickly we can try the following ways -

• By heating the mixture - On heating a solution, the kinetic energy of the solute particle increases which means the molecular motion of the particles increases, Increased molecular motion causes more solvent molecules to contact with solute particles and pull them with more force, usually resulting in more dissolving.
• By stirring the mixture - Stirring solute particles into a solvent increases the rate of dissolving because it helps to spread the solute particles throughout the solvent.
• By grinding the solute before it is put into the solvent - Smaller the solute particles, more is the rate of the reaction as it increases the area of it which is exposed to the solvent and hence the solute dissolves more quickly.

Answer 2

To make a solute dissolve more quickly in a solvent, it can be heated, it can be stirred or the solute particles can be grinded.  

Heating the solution:

• Heat increases the kinetic energy of the particles in the solution.
• When solution is heated, the heat energy is converted into kinetic energy and particles start moving faster which can result in increased solubility of the solution.

Stirring the solution:

• When the solution is stirred, solute particles gain that kinetic energy and it becomes easy to get soluble in the solvent.

Grinding of solute particles:

• Solute particles are grinded and their size is made smaller. Small sized particles easily gets dissolved in solvent.
